Specification of Letters Patent. A Patntdtay 17, 191i).

Application led october 29, 1909. Serial No. 525,251..

To all whomit may concern:

Be it known that I, TiroMAs G. PLANT, a

citizen of the United States, residing atA Boston, in the county ofSuiolk and State of' Massachusetts, 'have invented an 1mshoe treatinmachines. In the present em 4hodiment o the invention the luhricatingdevices are illustrated and described in connection with a machine fortreating the heels of 'boots and shoes, although, as will be obvious,the invention is not necessarily re-V stricted thereto.

As well understoodby those skilled inthe art it is com-mon to form'oeni'ngs in the heels of boots and shoes for t e, iiisertionvof thefasteninr means which eitherhold the parts of the' eel together or unitethe heel to the heel seat. It is ordinarily the practice,

also, tocompress the heel and while in this compressedcondition toprick'it. Obviously grr-ea: friction results by the passage of the awlsthrou h the heel, and the heat generated is liable to cause seriousinjury to the awls, as will be readily'un'derstood.

In the drawings :-Figure. 1 is a general side view of one form of 'heel'treating maf chine having the present inventionassociated therewith;Fig. 2 is a section on the line 2-'2 of Fig. et; Fig. 3 is a section onthe line 4 is an enlarged detailv of the upper portion of the machine ofFiO'. 1, with parts broken away to more clearbly disclose the elementsbeneath; and Fig. 5 is a section on the line 5-5 of Fig. 4.

While, as hereinbeforenoted, the invention is applicable to a largevariety of machines wherein awlsor prickers are used for piercingleatherthepresent embodiment of the' invention Vv,indicates itsfassociation with back View of one si Y a heeling machine "ofnthegeneral'typeset" -orth in my prior ,applieationf No. 412,727,

may he had.

Having reference to Fig. 1 the inacl'iinev frame 1 rising fromt-hesupporting base 2 may he of any desired construction to ac- 1908, towhich reference commodate the working parts, and itV has mounted in.suitable bearings therein the shaft 3 having appro riate cams e whichact lupon thel lower env s of rods 5 connected at their upper ends at 6to the cross`head '7, in all of which respects the generalcharacteristics of the machine shown in the drawings may correspond tothe like parts ininy prior application referred to, or otherwise asdesired.

Mounted insuitable bearings in the crossvofy head 7 is the turret shaft8 carrying the usual awls or prickers 9 and nail driving devices (notshown).- Connected to the turret .shaft 8 isthe segment gear 1G'operatively joined to the actuating shaft 11-bysiiitable gearing, as setforth in iny said application,

and said shaft 11 is 'itself actuated through a -gear 12 and the slidingrack har 13 which may be actuated in any suitable manner, or as pointedout in said application. i

, The turret which carries the awls andvnail sov driving devices ispreferably provided withl the guiding pins 14 and 15, said pins being'adapted to engage the perforation 4in a lunr 16 secured to the fixedcross frame 17 carried by the machine column, the construction beingsuch that one of said pins 14 or 15 will V engage the said perforationand serve to guide either the awls or nail driving devices as thecross-head rises and falls.

As usual in this class of machines, the

cross-head carrying the turret is first moved downward toV cause theawls to penetrate the heel and then raised to permit the awls to bemoved to one side by partial rotary movement of the turret, and the naildriving devices to be brought into coacting vrelation with the-fastenersto he driven, whereupon thecross-head is again caused to descend todrive' the fasteners. These features and characteristics of a heelingmachine are well understood and'need no .further elucidation.

Secured to the machine frame-inposition to receive the awls 9wheii'they' are in their inoperative position, asfindicated in Fig. 4,l:isiagcasing 18,.,Figs. 1, 2 and-3, said casingA 'ioo Y having anopenvtop, andV its side next adjai the turret head bein also open' toperiflitf the awls'to enter sid casing as' the tank 21, said tank beingdisposed below the cylinder 23, Figs. 1 and 3, in which fitsr a portion32 adapted to be engaged by the Ipin 29 to receive the securing bolt 30,the-con verly adjust the tension of the spring 25 and indicated in Fig.

lwill be depressed by the casing 13 and conveniently attached to themachine frame by Suitable means, such as the screw bolts 22.

Rising from the lubricating tank 21 is a hollow plunger or piston 24,normally `held in its raised position by means of a spring 25 connectedat oneend 26 to the interior of v`the piston or. plunger and at itsother end 27 to a suitable lug secured to or projected from the cylinder23. In order that the tension of the spring 25 maybe readily adjusted tosuit the conditions of'use, the lug or pin 27 is preferably carried vbyan adjustable bracket 28, Figs. 3 and 4, which is slotted atstructionbeing such that upon loosening the securing bolt 30 which istapped into the cylinder 23, the lug or pin 27 may be adjustedvertically in either direction to Apropcause it to normally 'hold the.plunger or piston 24 in raised position. Likewise Secured to theplunger or piston 24 is an `arm or lug 31, Figs. 3 and 4, having anupper 14 secured to the cross-head turret, w ien said pin and the .awlswhich are disposed arallel thereto are in their side position, as 4, andupon depression of the cross-head.

It will be noted that the cylinder 23 coinmunicates directly with theinterior of the lubricating tank 21, and froui the constructiondescribed it will be noted that the spring 25 will act to hold thepiston or' unger 24 in raised position, and as the crosshead descendsthis plunger-or piston v piu. 14, provided the awls are at the timebeing in inoperative or side position. It', however, thc awls andperforce their guide pin 1'4 are not in inoperative or side position asthe cross-head descends, but are in active position to pierce or prickthe shoe-heel, then the arm or lug 31 'and its connected piston orplungel' 24 will not betlepressed.

Rising from the lubricating tank 21 is an aspirator- 33 which is securedto the top of vthe tank by means ot a suitable nut and screw connection34. Passing through the tube of the aspirator is the inner tube 35 whichextends to near the bottoni of the tank, as indicated in Fig. 4.

Projecting from the end 36 of the aspiltop of the lubricating tank 21.

rator, Fig. 2, is a hood, preferably of conical form, leading into anopening 38 i in the wall of the casing 13, Figs. 2 and 3, l

currents through the aspirator, as indicated in Fig. 2.

In order that the oil' spray projected by the aspirator may be conied toproper action upon the awls 9, in the manner hereinbefore noted, thecross-head' 17 has secured thereto a casing 39, Fig. 3, disposed toreceive the ends of the awls, when said awls are in their side or raisedposition, as indicated i'n Fig. 4. The general characteristics of thecasing 39 are such that as the crosshead descends, said casing 39 willtelescope into the casing 18, thus inclosing the awls by a substantiallyclosed chamber for the act-ion of the lubricant. In order that thelubricant may pass into the awl chamber thus .created by the two casings18 and 39, the casing 39 is provided with an opening 40, Fig. 2, whichregisters with the opening 38 aty-tlie end of the hood 37, when thecasing 39 is in lowered position, as indicated in Fig. 3, theconstruction being such that the oil spray will be projected into thecasing 39l into intimate contact with the awls as they and the casing 39move downward under the action of the cross-head.

As hereinbeiore noted, the bottoni of the casing 18 is formed preferablyinclined, as at 20, Fig. 3, and connected tothe lower portion of thecasing, as at 41, Figs. 1, 3 and 5, is a drainpipe 42 through whichsurplus lubricant may pass. This drain pipe is preferably connected tothe top of the lubrieating tank'21and provided with a suitable strainerto prevent dirt and other foreign substances getting into the tank. @neconvenientform of such strainer is indicated in Figs. 4 and 5, whereinit comprises a suitable casing 43 containing fibrous or other strainingmaterial '44 connected, as at 45, with the drain pipe 42. Connected tothe strainer casing 43is a pipe 46 leading to the ln order that air maynot escape into the pipe 46 and find its way into the casing 18 upondepression of the piston or plunger 24, the inlet-to the pipe 46 ispreferably provided with a stop valve, one form of which is indicated inFig. 5. The stop valve may be conveniently provided with a ball 47contained in a suitable socket piece 48 and held to its seat 49 coveringthe inlet opening to the pipe 46 by means of a spring 50, the lower endof which rests upon a perforated plug 51, Athe perforation thereofleading to the interior of the lubricating tank 21.

`From the construction described it will be noted that as the plunger orpiston 24 descends and causes a spray of lubricant or oil to be impingcdupon the awls 9 for the time bei in inactive positon, the ball 47 willbe he d to its seat aad close the opening to the pipe 46; but, asthepiston rises in response to its sprin 25, the partial vacuum formedin the vlubrlcating tanlr will cause the ball 47 to drop from its seat49 and piern vmit a suctionto be exerted through the pipes `46 and-42,thereby 'causing withdrawal of 4 the supply opening 52, F ig. 4, the to353 of whichis disposed below the top 'of t e tank so that the tank cannever be completely filled. The inlet opening 52 may be convenientlyclosed' by means of a screw plug 5d, or otherwise.

From the characteristics of the invention as hcreinbefore set forth'inconnection with f the'illustrated form thereof, it will be noted that,when the awls are piercing the Work and are consequentlyin operativeposition, the guide pin lli will not contact with the arm or lug 3l sothat the lubricating device will lihevisefremain inactive. i/Vhen, hoW-gever, the awls are in their inoperative position, as indicated in Fig.a, and the crosshead descends, the pin le will contact with the arm orlug 3l carried by the piston 'or plunger 211 and Willdepress the same,thereby forcing a spray ot' lubricant through the aspirator and onto theawls which are at the time inclosed by the casings 39 and 18, and uponupward movement of the cross-head any surplus lubricant Will be drawnfrom the botgtom of the casing back into the tank ai'ltcr passingthrough ay suitable strainer.

Obviously changes and variations may be made in the Various elementswhich aredescribed as a convenient form ot' thc inven' tion Withoutdeparting romthe true scope or spirit thereof, which is definitely setforth by the claims, andwhile herein the a-Wls or pricking devices aredescribed as being lubricated, it will be apparent that Where desiredthe drivers for driving the nailsV or fasteners may be lubricated andthe term nicher-sy or pricking devices herein is 'intended to beinclusive of drivers.
